A further object of the inventionis to provide a machine of this'character which,`

in addition to breaking'the soil', willformV the same into ridges andcompress the dirt of the ridges sufficiently to prevent dispersal`thereof by ordinary rains and wind. Y Other objects and advantages ofthe invention will become apparent throughout the course of the'following description.

Inthe accompanying drawings, wherein for, the purpose of illustration isshown a preferred embodiment of my invention, and

wherein like reference'characters designate like parts throughoutFigurel is a side elevation of a machine constructed in accordance withmy invention, f

Fig. 2 is a `plan View thereof,

Fig. 3 is a fragmentary perspective showing the mounting of the cuttingdrum, and

Fig. 4 is a detail sectional view thereof.

,Referring now more particularly to the drawings, a frame is employedcomprising side bars 10 and front and rear endbars 10a and 10",respectively. Extending 'downwardlyV from ,theV front bar 10a are framesupporting members 11 which are connected at their lower ends with anaxle 13. This axle has mounted in its opposite ends vertical king .bolts14, upon which are rotatably mounted bell verse arms 16 forming supportsfor Vrotatable steering wheels 16a and-longitudinal arms 17having'connected thereto intermediate their ends a rigid link 17alwhich' assures simultaneous and uniformV action of the-bell cranks andof the steering wheelsV 16a. Therear end of the frame 10 has extendingdownwardly therefrom adjacent the ends thereof. supporting members 19having mounted therein an 4axle 2O 'on the ends had'to the accom' bars,

cranks 15 embodying `transof which are Vmounted rear supporting.;

wheels-21 provided with ground engaging lugs 22. y

The frame has mounted thereon rearlwardly thereof a driversseat 23.Arranged i adjacent to thedrivers seat is a steering wheel 23% embodyingthe usual steering shaft 24. To the lower end of the' steering shaft 24isV secured a beveledl gear24. which meshes` with the similar `beveled,gear 24"V carriedby the shaft 24e rotatably mounted upon the frame 10.The shaft 23c has opposite ly Ywound thereon flexible elements 25 whichpass about a series of pulleys 2 6 yand have their endsv secured tothe`ends of the arms 17 of the bell crank levers15, therebyj` providingadjacent the .drivers seat means for controlling the action of thesteering wheels. Y r

Arranged forwardly ofthe devicearel vertical guiding arms 28, suitably28a, and providedat their upper ends with inwardly extending portions 29secured to the side barslO of the frame. The verticalide members formslideways forvertically shiftable cured to these` yokes 30 arelongitudinally extending bars 40, provided forwardly withv portions 41paralleling thefframe. `These portionsl 41 have each mounted thereon astub shaft 42 Ahaving secured thereto sprocket wheels 43 and 44.Rearwardly of the stub shaft 42, the bars 40 are provided with .an insetterminating in a rearwardly extending angular lportion 45 causing therear ends of the angular portions45 the bars braced as .atV .j

members vor yokes 30.' Seat these sections to converge. At the againyparallel the frame and are ,providedk in these parallel portions withopenings 46 adapted for the reception of the axle47 of a roller 48.B-earwardly -of the roller thel bars are inbent, as at 49, and havesecured to the endsv thereof a slide 50. Securedto the frame is adownwardly extending guide 51 upon which the slide 50 operates. f V

Mounted upon the vframe rearwardly thereof and adjacent the drivers seat23, is a transverse rock shaft 52, having secured thereto an operatinghandle 53 which coacts with a segmental rack 54. This rock shaft hassecured thereto a normally horizontally disposed armv 55 connected withthe inbent ends- 49.A Mounted upon the side bars 10 of the frame andvextending transversely of the frame above theguide vby a link-56 arms 28is a' rock shaft 59 having a normally;

vertically disposed arm 60 secured thereto, which is connected by meansof link 6l to the normally vertically disposed arm 57 of the rock shaft52. The shaft 59 has secured n 50 is made of some flexible material,such as cable or the like. In fact, each of the arms of each of theshafts may be connected withits coacting member by a flexible connectionif desired. Y 4

A shaft 64 is provided having its ends-rotatably mounted in the slides30. This shaft has secured thereto a drum 65 of any desired constructionembodying a plurality of shares or digging teeth 66. Secured to theconverging portions of the armf40 are vertically disposed guides 67having their ends curved to correspond7 at the forward end of the guideto the curvature of the drum and at the rear end of the guide to thecurvature of the roller 48. The forward ends of the guides are providedwith transversely eX- tending portions G8 extending upwardly and securedto the guides and to the inbent portions of the bars 40 rearwardly ofthe stub shaft 42. Y Y' Secured to the shaft 20 adjacent each endVthereof is aV sprocket gear 69 of relatively large size. Rotatablymounted upon the frame adjacent the rear end thereof is a transverseshaft 70 provided upon its ends with relatively small wheels 71connected with the sprocket wheels 69 by means of chains 72. The shaft70 is likewise provided intermediate such ends with a sprocket wheel 73.Rotatably mounted upon the side bars of the frame, preferably slightlyrearwardly of the rock shaft 59, is a shaft 74 provided with a sprocketwheel 75 alined with the sprocket wheel 73 of the shaft 70 and connectedtherewith by a chain 76. The shaft.74 is provided upon its ends withsprocket wheels 77, each connected by a chain 78 with the sprocket wheel44 of the stub shaft 42 of the corresponding side bar 40. Mounted uponthe shaft 64 intermediate the ends of the drum and the guides 3() aresprocket wheels 79 connected by chain 80 with the sprocket wheels 43 ofthe stub shaft 42. It will be seen that when the device is moved alongthe ground the drum 65 will be driven from the rear wheels 2l and at ahigher rate of speed than such rear wheels.

In the operation of my device the same may be moved along the groundeither by means of power carried by the frame or may he drawn by atractor or corresponding device. As the device moves over the ground thedrum 65 is rotated, causing the shares 66 thereof to engage the groundwith a hoe-like` action. The dirt is thrown rearwardly from the drum bythese teeth or shares 66 intermediate the guard plates 67,which as theyconverge, cause the earth Vto be piled'in a space narrowerthan the widthof the cut over the piled dirt compressing the same,

formed by the drum. The roller passesV forming a ridge provided atY eachside with f more commonly designated ridge of dirt is formed having-uponeach side thereof a ditch or furrow in which theV It will be obviousIrear wheels operate.

that the lugs of these' wheels are therefore constantly in engagementkwith firm hard ground thus assuring an even drive for the digging drum..Y Y

As many changes are possible in the.

shape, size and general construction of var`i. ous portions of mydevice, as hereinbefore set forth, I do not limit myself to thev specieconstruction hereinbefore set forth, eX- cept as so limited by thesubjoined claims.

Having now described my invention, what Y l claim is:
